Web Background Music Summary

1. When setting up the background music of the Web page, the common method is to use embed tag, object tag and bgsound tag (<bgsound id= "snd"; loop= "2"; src= ""; volume= "0";/>)

2. Web applications and WinForm applications can use a timer timer, while Web site projects do not have a timer and can only use Window.settimeout () as a timer to cycle through a specific function window.settimeout (" Changemessage () ", 30000);

3, when modified JS page does not change, it must be JS error, you can press F12 into the developer tools to track

4, the Clientscript.registerstartupscript () function to print the JS script, can be tracked in the developer tool can also be viewed in VS (vs at run time will generate temporary script document in the solution)

5, HTML comments with <%----%>;//Double slash can also be used, but sometimes error

6, JS debugging is very troublesome, you can consider using alert () to judge, equivalent to a breakpoint, very useful.

7, object is not a function: A functional naming conflict, may conflict with the built-in function in HTML and may conflict with the Name property of this tag (the Name property of the label inside the form tag cannot be the same as the function to be called; you can have the same name without a form tag!) ！！ )

8. The ID of the control in the page is unique, so the control can be accessed across the page by ID

9,BS get relative path : string url = Server.MapPath ("");
